Specification of Letters Patent.

Patented June 26,1906.

Application filed April 17, 1906. Serial No. 312,247.

struction and increase the efficiency and utility of devices of thischaracter, whereby the calks may be readily attached to or detached fromthe shoe without removin the same from the hoof, so that winter-ca ksmay be substituted for summer-calks or broken or worn calks replaced asrequired. j

With this and other objects in view, which will appear as the nature ofthe invention is better understood, the invention consists in certainnovel features of construction, as

hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this speciiioation, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of the embodiment ofthe inventioncapable of carrying the same into practical operation. l

In the drawings, Figure 1 is a perspective view from beneath of ahorseshoe with the improvements applied. Fig. 2 is a perspective view ofan approved form of toe-calli detached. Fig. 3 is a perspective view ofan approved form of heel-calli detached. Fig. 4 is a transverse section,enlar ed, through the heel portion of the shoe wit one of the improvedcalks applied.

The improved device comprises a horseshoe calkl consisting of the bodyportion 10 of any form, either of the Vsharpened wintercalli orthe dullsummer-calli, as may berequired, the improved calk being arranged forready attachment to or detachment from the shoe without removin the samefrom the hoof, so that worn or roken calks may be easily replaced orthewinter-calks changed for summer-calks, or vice versa, as circumstancesmay require.

The bodyof the calk isv provided with a threaded stud 11 and withlaterally-extendstrain or from blows while in use.

ing arms 12 13, the threaded stud adapted to engage a threaded aperturein the body of the shoe (represented at 14) and the arms 12 13 adaptedto be bent around the portions of the shoe adjacent to the apertures, asrepresented, to firmly lock the calk to the shoe and prevent its workingloose or rattling under the severe strain to which devices of thischaracter are subjected.

In Fig. 1 is represented a horseshoe with the toe-calk and theheel-calks in position thereon, the toe-calli having its lateral armsbent around the toe portion of the shoe and the heel-calks with theirlateral arms bent around the heel portion of the shoe. j

In Fig. 2 is shown an approved form of toecalk with the bearing portionin the form of three spaced spurs, and in Fig. 3 an approved form ofheel-calli is shown with the body portion'in the form of a single spur.

' In Fig. 4 is shown a transverse section of the heel portion of theshoe with one of the heel-calks attached thereto, the lateral arms beingshown in full lines bent around the adjacent portions of the shoe, whilethe arms are shown`in their opened or distended posi- Y* tion in dottedlines.

The device is very simple in construction, can be very readily applied,and holds the calk iirmly in lace and effectually obviates all tendencyof) the calk to work loose under When the form of calli shown in Fig. 2is employed, the spurs may be connected by ribs 15 to stiften andsupport them.

I-Iaving thus described the invention, what is claimed as new is- Ahorseshoe having threaded apertures at the toe and heel portions andcalks having threaded studs for engaging said apertures and withlaterally-extending arms opposite said studs and adapted to be bentaround the portion of the body of the shoe adjacent to the calk and itsstud and reinforcing the same.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in the presence of two witnesses.
